Were they there to help the Sixers make a recruiting push for the services of The King?

"Absolutely, absolutely," Wentz said Wednesday when asked by reporters after minicamp practice if it was a recruiting trip. "I hope he's coming.
Ertz and I were there the other night. Unfortunately he lost, I didn’t really care who won that game, but seeing him live — we decided to make it a recruiting
trip."

Ertz has been an outspoken fan of James for quite some time, as is visible on his social media.

Regardless of who the Cavs play, winning one game in the finals with this team would be a bigger achievement for Lebron than winning the East... But I wouldn’t count him out!
